INVENTOR AR Graff BY ATTORNEY I claim as new and desire to III Thisinvention is not intended to be restricted in scope to the preferredembodiment shown, but contemplates such modi fications as come withinthe spirit and scope of th claims Having thus described my invention,what secure by Letters Patent, is

1. vAn attaching plate for auxiliary springs having at opposite endsdownwardly bendable lugs adapted to engage the plate support, upturnedinwardly bendable lugs adapted to center and interlock with the bottomcoil of a spring and a clip connected to the overhung sides of the platemidway between its first mentioned lugs.

2, An attaching plate for auxiliary springs having at opposite endsdownwardly endable lugs adapted to engage the plate support, upturnedinwardly bendable lugs adapted to center and interlock with the bottomcoil of spring, a clip connected to the overhung sides of the'platemidway between its first mentioned lugs, and a heavy metal yoke for theclip disposed transversely to the downwardly bendable lugs and adaotedto reinforce said overhung sides oi the plate.

3. An attaching plate for auxiliary springs having at opposite endsdownwardly bendable lugs adapted to engage the plate support, upturnedinwardly bendable lugs adapted to center and interlock with thebottom'coil of a spring, aclip connected to the overhung sides of theplates midway be tween its first mentioned lugs, and a heavy metal yokefor the cl'p disposed transversely to the downwardly bendable lugs andadapted to reinforce said overhung sides of the plate, said yoke havingits ends rounded to fit snugly as a centering block in the bottom springcoil.

a. The combination with a vehicle aizle having a top flange, oi a baseplate for an auxiliary spring having extensions overlying the axle, lugson said extensions adapted to be bent over and interlock with the edgesof the axlestop flange, means to fasten the center otthe plate to theaxle, and side extensions on the base plate at right angles to the axle,the tops of all such extensions being uprm 1,3e5,ees

turned and adapted to be bent over and positively engage the base coilof a spring thereon.

5. A base plate adapted to attach an auxiliary spring to an axlecomprising a formed of bendable sheet metal having pairs of end and sideextensions, lugs on the opposite end extensions adapted to be bent overand interlocked with an axle, a clip yoke set trans ersely across thecenter of the body with its ends reinforcing the side'extensions, a clipadapted to straddle the axle and fasten through the side extensions tothe yoke, and upturned lugs on the several extensions adapted'to be bentover the base coil of a spring.

6. A base plate adapted to attach an auxiliary spring to an axlecomprising a body formed of bendable sheet metal having pairs or. endand side extensions, lugs on the op posite end extensions adapted to bebent over and interlocked with an axle, a clip yoke set transverselyacross the center of the body with its ends reinforcing the sideextensions, a clip adapted to straddle the axle and as ten through theside extensions of the yoke, and upturned lugs on the several extensionsadapted to be bent over the base coil oi a spring, one extension beinglonger to bend over the double coil thickness where the end laps thebottom coil. 7

7. A base plate formed of bendable sheet metal in the form of a crosswith upturned spring engaging lugs on its ends and spaced pairs of axleengaging lugs, a clip connected to the'plate'ends o rerhnn g at eachside from the ale id disposed midway between and at r nt angles to theplane of the axle enlugs, and heavy metal clip yoke overlying theoverhung plate ends, said spring engaging lugs being adapted to receivethe base coilv oi"- tween them and to be bent upwardly over said coil tosecure it to the plate and said clip forming a diagonal centering blockfor said base coil, substantially as described.
